Yet another classic contribution from Mr. Greenspan

“There were unintended consequences to almost every action I was involved in” as Fed chairman, said Mr. Greenspan, who himself cut interest rates to help stave off a bond-market crisis in 1998, and later was accused of helping inflate the stock bubble of the late 1990s. “If we anticipated the unintended consequences that were going to happen we might have changed the policy"

Also added that it was impossible to forecast all the consequences of government action.

Imagine that! There is no way to "anticipate" the future, I guess that's why it is called - "the future".  But to first downplay and later justify your actions, just reeks of moral hazard, hindsight bias, and a lack of accountability...

There will be "unintended consequences" in EVERY decision we make, but one should not use this fact as further reasoning to embrace a failed macroeconomic theory.

Shouldn't he be considered senile already?
